NGX-1 NMEA 2000 Gateway
About the NGX-1
The NGX-1 from Actisense is an NMEA certied device which can operate in two distinct modes,
depending on user requirements.
Transfer Mode : NMEA 2000 to PC interface(ISO or USB variant)
or
Convert Mode : NMEA 0183 <-> NMEA2000 bi-directional converter(ISO or USB variant)
Modes explained
In Transfer Mode, (Status = ) the NGX-1 operates as an NMEA 2000 to PC interface, providing
an easy way to link a PC to an NMEA 2000 network. In this mode it makes it possible for software
applications to read and write to an NMEA 2000 bus while maintaining network integrity.
In Convert Mode, (Status = ) the NGX-1 operates as a data converter, allowing the older NMEA
0183 networks & equipment to co-exist with modern NMEA 2000 networks. It provides a
bi-directional facility allowing NMEA 0183 sentences to be converted into NMEA 2000 PGN messag-
es, and vice-versa. A default set of conversions is pre-congured which covers most standard conver-
sion requirements (including AIS conversion from NMEA 0183 to NMEA 2000).
To adjust these conversions (e.g. to congure fast heading or bi-directional AIS) please see page xx
for more details.
Note: Not all PGN messages have an equivalent NMEA 0183 sentence. Many NMEA 2000 PGN’s
have been created and have not been not been transferred back to the NMEA 0183 standard. Please
see the conversion list on our website - www.actisense.com.
NGX-1 Variants
ISO Variant (NGX-1-ISO):
The NGX-1-ISO is supplied with a 0.75m NMEA 0183 4-wire “differential pair” cable for connecting
directly to NMEA 0183 equipment. NMEA standard wire colours are applied.
This allows for the NGX-1-ISO to be installed directly to an NMEA 0183 device without the need for
further set-up in most circumstances.
USB Variant (NGX-1-USB):
The NGX-1-USB is supplied with a 1.8m USB cable (USB plug type B) for direct connection to a PC or
laptop.
This allows the NGX-1-USB to interface with compatible apps. on a PC and run directly without the
need for further set-up in most circumstances.

8Active Research Ltd 2023
Powering the NGX-1
Both variants of the NGX-1 (ISO & USB) receive power supply when connected to a correctly powered
and terminated NMEA 2000 backbone. See page 9 for the minimum bus requirements.
Note: Make sure that the blue ‘Power’ LED is illuminated for correct operation of the NGX-1. See LED
behaviour table on page 23.
Connecting to a USB Port
For USB variants of the NGX-1, simply plug the USB cable on the NGX-1 in to a PC USB port and the USB
driver installation will begin. For ISO variants of the NGX-1, a USB to serial converter cable can be used
to connect to a PC USB port. For wiring the NGX-ISO cable refer to the instructions given on pages 11
& 12.
USB Driver Installation
Windows 7, 8, 10 & 11 will automatically install the drivers from Windows Update if there is an active
Internet connection the rst time the NGX-1 is plugged in. If the PC is not connected to the Internet or
if the USB driver does not install automatically on the rst installation of the NGX-1, the ‘Update Driver
Software’ option in Device Manager will need to be used to install the USB drivers manually. Please visit
the Actisense website at www.actisense.com to download the latest drivers should they be required.
Connecting to an NMEA 2000 network
The diagrams on page 9 show how each of the NGX-1 variants sit on an NMEA 2000 network.
NGX-1-ISO
The most common use case for the NGX-1-ISO is as an NMEA 0183 <-> NMEA 2000 converter.
In this situation, the NGX-1-ISO is wired directly into an NMEA 0183 device allowing data to pass
through the NGX-1, be converted, and then be placed directly onto the NMEA 2000 bus. The data-ow
is bi-directional allowing NMEA 2000 PGN’s to be converted back to the NMEA 0183 device if required.
Note: The NGX-1-ISO may require some additional set-up to allows the bi-directional
conversion of AIS sentences. This uses our free Toolkit software, and requires access to a
serial-USB converter. Additionally, conguration can be accomplished using an Actisense
NGT-1-USB if available.
Connecting the ISO-wires with a serial-USB converter also allows a direct connection to a PC/laptop. In
this situation, the NGX-1-ISO can utilise both modes of operation (Transfer or Convert).
NGX-1-USB
The most common use case for the NGX-1-USB is as an NMEA 2000 to PC interface (Transfer mode),
allowing a compatible PC application to interact with an NMEA 2000 network. It can however be placed
into ‘Convert’ mode should you wish to convert NMEA 2000 data back into NMEA 0183 to be viewed on
any PC application which utilises NMEA 0183 (eg. OpenCPN).
Actisense Software
Actisense supplies the following free software which will be required to congure the NGX-1 into the
required state.
• NMEA reader
• Actisense Toolkit
• Please visit https://actisense.com/nmea-software/ to download this software.

Connecting to an NGX-1-ISO
There are several ways which the NGX-1-ISO can be connected, but the most common requirement will
be to integrate an NMEA 0183 device to an NMEA 2000 network.
The NGX-1-ISO communicates using the RS-422 protocol which requires that data is sent and received
using two pairs of wires. These are often termed as a “differential” pair.
The two pairs of wires are normally designated as:
• Talker pair (A+ / B-): This is the pair over which data is sent from an NMEA 0183 device.
• Listener Pair (A+ / B-): This is the pair over which the device receives NMEA 0183 data.
Currently, the specied NMEA 0183 signal colour coding for individual wires is as follows:
• Talker (A/+) -WHITE
• Talker (B/-) - BROWN
• Listener (A/+) - YELLOW
• Listener (B/-) - GREEN
The wiring on the NGX-1-ISO follows the above convention for the data pairs, and if followed, should
make wiring NMEA 0183 devices which have the same colour coding easier to achieve. Please refer to
the instructions of the device which you are connecting to your NGX-1 for more details.
The following diagrams show how to connect to the most popular devices:
A- Connect to an NMEA 0183 Device
Connect the NGX-1-ISO as shown in the diagram overleaf. If the device conforms to the NMEA 0183
standard, it should have the appropriate talker (A/+ & B/-) and listener (A/+ & B/-) pair clearly marked.
Consult the manual or contact the manufacturer if unsure.
B- Connect to a PC with an Actisense USG-2. USB to Serial Gateway (RS-422)
Should you require to connect your NGX-1-ISO to a PC, you can attach an RS-422-Serial converter such
as the Actisense USG-2.(https://actisense.com/products/usg-2-nmea-0183-converter/)
Note: To communicate with your NGX-1, select the USG-2 COM port displayed in “Device Manager”
C- Connect to a PC using and RS-232 Serial to USB converter
The NGX-1-ISO can also be connected to an RS-232 Serial converter if required. There are many such
devices available and the diagram depicts a standard general outline only. The two B/- wires are
connected together at a common ground.
Note: To communicate with your NGX-1, select the COM port for the converter in “Device Manager”
D- Connect to a serial port using a D-TYPE 9-pin socket
The NGX-1-ISO can also be connected to the older D-type 9 pin serial port should you wish to connect
it directly into a serial port card on your PC. The serial connection is RS-232 and the two B/- wires are
connected together at a common ground (pin 5).
